WebFeb 28, 2024 · In this study, we asked whether these reactions in solution are diffusion controlled, which reaction model and thermodynamic cycle describes the complex formation, and if there are any functional differences between avidin and streptavidin. We have studied the biotin association by two stopped-flow methodologies using labeled … WebStreptavidin and its homologs (together referred to as streptavidin) are widely used in molecular science owing to their highly selective and stable interaction with biotin. Other …
Rapid one-step biotinylation of biological and non-biological surfaces
WebThe strong biotin-streptavidin interaction limits the application of streptavidin as a reversible affinity matrix for purification of biotinylated biomolecules. To address this concern, a series of single, double, and triple streptavidin muteins with different affinities to biotin were designed. The strategy involves mutating one to three strategically … WebMay 13, 2024 · We referred to Liu et al. and made some changes; the reaction system consisted of biotin-d(PEG) 4-NHS ester (4 mg/mL), Ru ...
